Deep within Tehran, hidden from prying eyes, scientists are working on a banned device. Their intention is to propel Iran into the elite club of nuclear-armed nations – and seal its domination of the Middle East. Britain’s intelligence agencies have someone on the inside but first he must get out of Iran. Due to rendezvous with MI6 agent Luke Carlton, the mission goes bloodily wrong. Luke needs to be extracted. MI6 is presented with an opportunity to recruit someone with unique access to the leader of the IRGC hardliners. And Luke is chosen to reel them in. Going into Iran undercover is dangerous enough, but then a senior British government minister is kidnapped, his close protection officer killed and Britain is presented with a terrifying ultimatum.
